Zhizha rasvika, uye chinhu chinonyanya kuvhiringidza kune wese munhu kuchengetedza chikafu. Maitiro ekuona kutsva kwechikafu chave nyaya inopisa mazuva ano. Saka tinofanira kuchengeta sei michero nemiriwo mitsva muchirimo chinopisa kudaro? Mukutarisana nemamiriro ezvinhu aya, mumakore achangopfuura, tsvakurudzo yesayenzi yakawana inhibitor inoshanda ye ethylene chiito -1-MCP. Iyo 1-MCP inhibitor haisi chete isiri-chepfu, isingakuvadzi, isina zvisaririra, uye ine hushamwari kwezvakatipoteredza, asi zvakare inoshandiswa zvakanyanya kuchengetedza michero, miriwo, uye maruva. Pazasi, isu tichasuma iwo chaiwo ruzivo nezve 1-MCP chigadzirwa.
Chii chinonzi 1-MCP?
1-MCP, inozivikanwawo se1-Methylcycloprotene,CAS 3100-04-7. 1-MCP inoshanda ethylene inhibitor iyo inogona kuvharidzira kutevedzana kwehupenyu uye biochemical maitiro ane chekuita nekuibva kwemichero kunokonzerwa ne ethylene, inhibisa chirimwa kufema simba, zvinobudirira kunonoka kuibva kwezvibereko uye kukwegura kufambira mberi, kuchengetedza kutaridzika kwepakutanga uye mhando yemichero nemiriwo. kwenguva yakareba, kuderedza kubuda kwemvura, kuderedza kukuvara kwepathological uye kuora kwe microbial, Kuchengetedza hutano hwekuchengetedza michero. Uye 1-MCP haina chepfu uye yakasara yemahara, inosangana nezviratidzo zvakasiyana-siyana zvekuchengetedza mavhidhiyo emunyika, uye inogona kushandiswa nechivimbo.

1-MCP application
Pamberi pekushandiswa kwe1-MCP, nzira dzakawanda dzekuchengetedza nekuchengetedza kwemuviri dzakagamuchirwa: 1. firiji yepasi-tembiricha, 2. inodzorwa kuchengetedza mhepo, uye 3. kupisa, chiedza, uye microwave kurapwa. Zvisinei, idzi nzira nhatu dzinoda vanhu vakawanda uye zviwanikwa, uye nguva yakareba uye ipfupi. Tsvagiridzo yakaratidza kuti 1-MCP inogona kunyatso kukwikwidza kusunga kune ethylene receptors, kunonoka kuibva kwemichero uye kuchembera. Nekuda kwezvimiro zvayo zvisina chepfu, kushandiswa kwakaderera, kushanda kwakanyanya, uye kugadzikana kwemakemikari zvimiro, parizvino inoshandiswa zvakanyanya mukuchengetedza michero nemiriwo, ine yakakwira musika kushandiswa uye kusimudzira mwero.
1-MCP haingodziviriri kana kunonoka kuitika kwekukwegura kwepanyama mumiti, asiwo ine huturu hwakaderera. LD50> 5000mg/kg chaizvoizvo chinhu chisiri chepfu; Iko kusungirirwa kunoshandiswa kwakadzikira zvakanyanya, uye kana uchigadzira michero, miriwo, nemaruva, kunyura mumhepo kunongoda kuva miriyoni imwe chete, saka yakasara mumichero, miriwo, uye maruva mushure mekushandiswa yakadzikira zvekuti haigone kuonekwa. ; 1-MCP yakapfuurawo kuongororwa kweUS Environmental Protection Agency (EPA webhusaiti chiziviso) uye inonzi yakachengeteka uye isina chepfu, yakakodzera kushandiswa mumaruva nemichero nemiriwo, uye yakachengeteka kuvanhu, mhuka, uye zvakatipoteredza. Iko hakuna chikonzero chekumisikidza dosage kurambidzwa panguva yekushandisa.
Chii chinonzi musika maonero e1-MCP?
Kune nyika dzekurima, nhamba huru yemichero nemiriwo mitsva inogadzirwa gore rega rega. Nekuda kwekusakwana kwekusimudzira kweinotonhora cheni Logistics yezvigadzirwa zvekurima, inenge 85% yemichero nemiriwo inoshandisa zvakajairwa zvinhu, zvichikonzera kuwanda kwekuora uye kurasikirwa. Izvi zvinopa nzvimbo yakakura yemusika yekusimudzira uye kushandiswa kwe1-methylcyclopropene. Mhedzisiro yekutsvaga inoratidza kuti 1-methylcyclopropene inogona kuderedza zvakanyanya kunyorova uye kuora kwemichero nemiriwo, uye kuwedzera hupenyu hwavo hwesherufu uye nguva yekuchengetedza. Izvi zvinopedzisa kuiswa kwe1-MCP. Kana iwe uchida kuziva zvakawanda nezve chigadzirwa, ndapota ndisiire meseji.
